To dll whom it may comam: I

Be it known that l, JosEPn P. LAVIGNE, a' citizen of the United States. of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new useful Improvements in Quick-Opening Valves, oi which the following is a specification, referfully hereinafter described and particularly pointed out in the claims.

In the drawings, Figure l is a vertical central section through an angle valve embodying my invention; and' Fig. 2 is a horizontal section thereof on line 2 2, Fig. 1 l

, A represents the casing, having an vangle passage therethrough, a seat B and a disk C, in'ordinary form of disk casing C, adapted to be moved to and from the seat B to open and close the valve. The disk casing has on it a flange c in which is engaged the lower enlarged end of the hol1ow, valve stem D. This valve stem projects up into the cap F, which as usual is screwed into the main portion o the casing A. At the top this valve stem D is provided with the lateral iiange a, which engages the spiral or quick thread .l on the interior of the .Cap-

' G is an operating stern journaled in the central apersquared to enter the squared aperture E in the valve stein, so that in turning the operating stem the valve 'stein will turn therewith.` The valve stem slides on p the valve and its stem in relation to the operating ,stem

on the opening and closing movementsthereof. At the ltop this bore or aperture bzxnay be closed by a screw Specication of Letters liatent. Application led December 2,1905. Serial N o. 290,036.

Patented July 16, 1907.

K is an operating handle which is secured in the upper end of the operating stem and may be provid ed with 'a pointer e to indicate the position of the valve.

L is 'the usual packing gland 'around the upper portion of the operating stein. l

The operatingstern is provided with a collar 'l which 'enters'a co'untervboie in thelower portion of the cap,

which counterbore is-screw-tb'readedto receil've the annular nut'or screw plugM. {This screw 'plug beingv screwedin position, as shown in Fig. l, the contact with the 'collar z' will prevent any undue vertical movement of the operating stemfandat the same time allow it to freely rotate i The .parts being thus constructed, vit is obvious that if the handle K is turned it will turn the operating .stem and throughthe squared connection between the operating stem and valve stem the valve stem will likewsexbe rotated and the lug a engagngthe spiral or thread .l will be nioved up or down according to the 1. In a quick-opening valve, the combination of the easlng, `the valve disk, a stem therefor engaging a quick thread, -an operating stem siidingiy eengaging the valve stern, and :i guide 'for the valve stem engaging the operat ing stem. i

I 2. In a.`quick-openlng vulve, the combination `o the cas- Ving, a valve disk, a'texn .therefor engaging a quick thread,

an operating stemslidingly engaging the vvalve stem, und a guide rod extending through the valve stem and engaging an axiaiguideway in the operating stein.

3. In a quick-opening valve,.the combination of the eas ing;F an upertured cap therefor, n rotary operating stem journaled therein, said cap having a screw-threaded c'ountei-bore at the lower end of the aperture, a collar on said stem, an annular' screw plug surrounding the operating stern, screwed into the counterbore 'and engaging the underside of the collar, a valve arranged to seat in the cas lng, anda stein for the vulve having n telescopic engage ment with theoperating stem, substantially as) described.

In testimony whereof I aiix my signature in presence of two witnesses.
